COMBINATION-TOOL.

Patented July 23, 1907.

To all rl imm it may concern: Be it known that I, lTn'nM/m Gon'rr-msnAHLBERG, a

citizen ol' the Unitedv States, residing at Burlington, in

the county of Des Moines and State of Iowa, have invented certain newand useful Improvements in. Cour bination-Tools, of which the followingis a.speciljca- 'Lion, reference being had therein to the accompanyingdrawing.

This invention relates to a combination tool or'instrunient, the objectbeing to provide a device of this- I .to adapt the device inpracticaf'nse, so as to perform .the different functions, as indicatedabove to coincide with the respective professions.

- This invention compriscs further objects and comhinations oi elernentswhich will be hereinafter more fully described, shown inthe'accornpanying drawings,

and the novel features thereof will be pointed outby the appendedclaims.-

. To obtain a full and correct'understanding ot the de- I tails ofconstruction, combinations of features, elements and advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith, wherein Figure '1 is aperspective view showing the device ready for. i1se,as a. surveyorsinstrument or. an architects level. Fig. 2 is an elevation showing thedevice,,a sacar enters level, and also displaying the v gage extensionrule and calipers. Fig. 3.31s an elevation showing the device; as ac'arpenters square. Fig.

, 4 is asectionalview 'ohJlineA A of Fig. 3. Fig 5 is a 4O iragmentalview showingthe gage extension rule e'xtended, andfrecess for receivingthe blade, which forms a part of the carpenters square. Fig. 6 is adetail per- I spoctiv'i view,lshowing more clearly the calipers. Fig.

"7 is an elevatioh of one of the hinged sights, showing more clearly thefine wires disposed at right angles to one another. V

I Making renewed reference to" the accompanying drawings, whereinsirnilar reference characters indicate corresponding parts in theseveral illustrations, by figures, 1 designates the legs of thetripodQwhen the com-.

bination tool is used'in connection therewithasa surveyors instrnment,which legs are biinr'cated'as shown at Z, to receive the-lugs 3, of thering plate 4, which logs are securely" clamped within. saidbiiurcations, by 5 5 means otthe bolts and winged nutsoi'and 6; thisring penters or architects level.

' plate 4 is provided with tl'nnnh screws 7 having conical shaped ends,which are adapted to engage the inner ring plate 8, which also isprovided with thumb screws. 9, disposed at right angles to the screws 7,which screws 9 also having conical shaped ends ffiigagc' the spherical vshaped ball 10, which is provided with an'npwardly extending shank 11,which supports the diskf12, 'as shown in Fig. 1. These ring plates andthumb screws are provided for the purpose of regulating and insuring theequilibrium of the device s/hen need as an architects or survcyorsinstrument. The disk 12 is provided with a plurality of clamping lugs13, which clamp the base, 14, oi'the ll-shaped member 15, the oppositeendpertions of which, being bifurcated as at 15 to receive thecombination tool, which is securely 70.

held therein, by means of the thnrnb screws 1-7.

When the combination tool whichis carried-by the .Ushaped member isproperly adjusted in the desired position, the'clainping elongated plate18 which i's hinged as at 19, securely holds the parts thereofin a rigidand fixed relation, by operating the thumb screw 29, which presses thesaid-plate 18 down upon the ball 10,. which will cause thering platesand thu'mh'screws. to irictionally bind; the'plate-lS is provided withan elliptical shaped opening 21 to receive the shank'll of the ball 10,as shown in Fig. 1. The combination tool comprises a pair oi Irfernbers2 5m 23, hinged together-es M24, the member 22 7 being provided withgraduations 25, as shown in Figs.)

1, 2,.and 3 of the drawings, so as to adapt the device as a .8 5. rule;the member 23, is provided with a pair oisights,-.. f 26 and 27, whichare hinged as at 28, the sight 26js op-.-

e1'tured at 29 and 30, and which apertures are in alinement with theaperture 31, and slot 32, of the si ght -27, 1 which aperture 31 andslot 32 are provided with a sight-, ing point 33, formed at the crossingof the two pieces of wire 34 and 35, disposed at right angles to,oneenfothcr, as shown the member 23 is recessed'a-way'as at 36, toreceive the sights when closed, so as to render the devicecoinparatively compact in form when not in: use, said inembor 23 is alsoprovidcdwith-a level glass 37, so that the device may oo-used as anordinary' car- When it is desired tones the device, as a surveyorsinstrument, assemble the parts as shown in Fig.1, then'elamp an ordinarycompass, between the horizon tel portion oi the U-shaped member and themember.

. 22 Jr the combination tool, the pressure of which being,

suflicient to prevent displacement of said compass, after which proceedwith the use of the instrument When the device 'isnsed as an architectslevel, the parts are assembled as shown iiil ig. 1, but dispensing I'with the compass, the rule is then set on the corner of j the building,after which the procedure is a's'with M1 square, as shown in Fig. 3 ofthe drawin 41, which is pivoted at 42, as shown in Fig. 29f the.drawings, and when the tool is closed, as shown in Fig. 1

shown in dotted lines.

Pivotally mounted on a pin 43, of the member 22 is n.

10 3 the plumb bob is received vrithin said member 23, as

blade fl' having a plurality of graduations of degrees a 45, this bladeis used to partly form a carpenter's The member 23 is provided with arecess 46, in the free end 4hereof, to receive the blade 44 when thesaid member isclosed, as shown in Fig. 3. Also pivotally mounted uponthe pin 43, is a pair of hermaphrodite calipers;

2U 4'7,-'1;hat is, a pair of calipers which may be used either I formeasuring widths and thicknesses or diameters of; openings andperforming similar functions, as will be 7 clearly understood from thedrawings. The member} 22 is recessed longitudinally as shown at 4.8, tore-f is closed as shown in Figs. 1 and 3 of the drawings.

The device when used as a square, the parts of the 25 'ceive the blade44 and the calipers 47, when the tool E tool'assume the relativepositions as shown in Fig. 3 of the drawings; the device may be used asa carpal:

. {:6 of the member 23 thereby allowing the plumb hob to swing freelyoutward, thus allowing the device to peiiorm' the iuncti'ons of acarpenter's level, as shown in Fig. 2 of the accompanying drawings.Rises,

slopes, or inclinations may be gaged or measured by allowing the partsof the device to approximately as 30 terfs level, by resting the end ofthe blade in the recess Bums the positions as shown in Fig. 2, butwithout one playing the plumb bob, then allow the blade 4 t itic throughthe recess 46 until the desired'position is reaehedby the member 23,after which'the number of degrees at the stopping location of the member23 is earl, thus giving the measuring degree of the inclinw tion.

It is to be understood that various changes may be made in the detailsof. constri1etion,' combination of features, and elements, without inany way departing from the spirit and scope oi the invention covered byI the claims thereof; it being also understood, that What evervariations are adopted must fall within the scopeof the appended claims.

From the foregoingthe essential features, elements and the operationoi'tlie device, together with the simplicitj thereof,.wi1i bra-clearlyapparent, and, when manufactured in accordance with the invention; anirieitp'ensive market will be easily obtained therefor.
